Zill O-15 was a seedling of ‘Jakarta’ from the breeding program of Gary Zill in Boynton Beach, FL.
It is a medium-sized mango, ovately shaped and turning yellow at maturity. The flesh is fiberless, yellow, and firm. The flavor excellent,though can be highly resinous, reminiscent of Jakarta but probably sweeter, belonging in the Indian/West Indian flavor class.
The original tree is productive, but the fruit tend to ripen in a very short span, only a couple weeks.
We topworked a tree into O-15 in 2017 for evaluation. In 2019 this tree flowered and set fruit well, but did not retain any of its fruit to maturity. It finally fruited well in 2020 and had multiple crops.
Flavor: Indian/West Indian
Country: Florida - USA
